Aim In patients with ILD, a static expiratory pressure–volume curve of the lung is generally
shifted downward and rightward and spirometry results reveal reduced vital capacity …

Introduction In the field of pulmonary medicine, respiratory mechanics and physiology are
obviously affected by most pathological lesions and diseases, either primary disease or part …

Objective: to determine changes in the parameters of impulse oscillometry (IOS) in patients
with idiopathic pulmonary fibrosis (IPF) and find their correlations with lung damage …

Impulse oscillometry (IOS) is an emerging tool to assess lung function in chronic respiratory
diseases, more often in preschool children and patients who are unable to perform …

Background Impulse oscillometry provides useful clinical information that prominently
includes functional assessment of small, peripheral airway behavior beyond that available …

Background Small-airway affection and its relation to clinical status in asthmatic patients
became an increasing interest during the last decade. Spirometry is a basic diagnostic tool …

BACKGROUND: Forced oscillometry is a non-invasive method to measure respiratory
resistance and reactance. In this study, we investigated the characteristics of measurements …

Impulse oscillometry (IOS) is a good method for measuring airway resistance. The aim of this
study was to assess the diagnostic contribution of IOS combined with bronchial dilation test …

Interstitial lung diseases (ILDs) are functionally characterized by a restrictive ventilatory
defect due to a reduced distensibility of the lung parenchyma. ILD patients also show a …

Background: Restriction is a typical functional abnormality in interstitial lung disease (ILD)
patients, but is not always present, especially in the early stage of the disease. The greater …
